Public bug reported: I am using the beta version that works very well but there are updates that the system cannot perform and comes with these erros. Not all updates can be installed, asks to run a partial update and them is says: Unable to get exclusive lock, This usually means that another package management application (like apt-get or aptitude) already running. Please close that application first. Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: The package 'unity' is marked for removal but it is in the removal blacklist. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu This is most likely a transient problem, please try again later.
